I'm considering booking a flight with WOW Airlines and since it's the first time I hear about it I did some research on google and I find mostly good reviews.
However, while looking for the safety ranking, I found out that WOW Airlines is not IOSA certified.
What is IOSA Certification? The IATA* Operational Safety Audit (IOSA) certification audit is an internationally recognised and accepted evaluation system designed to assess the operational management and control systems of an airline. IOSA uses internationally recognised audit principles and is designed to conduct audits in a standardised and consistent manner. Airlines are re evaluated every two years. Registering for IOSA certification and auditing is not mandatory therefore an airline that does not have IOSA certification may have either failed the IOSA audit or alternatively chosen not to participate. *IATA (International Air Transport Association) - See more at: http://www.airlineratings.com/ratings/313/wow-air#sthash.oLSquDNX.dpuf
While I understand this is not mandatory, does this mean they have low safety standards or said standards are enforced in other ways?
